The Diana character is obnoxious AF and doesn't really add anything to the central plot so far (it did briefly, but not it feels like they are just trying to SHOVE her into the plot anyway they can because she is the second female lead apparently), but she's SO CREEPY

I don't buy the romance between Zero Nine and DaDa, the are more like symbols to each other than actual people - To DaDa Zero Nine is someone who pays attention to her the way her ex never did, and to Zero Nine she's just "Girlfriend", and it is annoying how he never uses her actual name.

Nam Bo Won is okay most of the time, as is the rest of REAL Team

I like Ma Wang Joon, but not enough to watch the drama just for him, plus he did do various crappy things to his gf at the beginning.

Only character I 100% liked was his noona manger
